Sun Java System Messaging Server 6.3 Administration Guide Logging In for the First Time

When a Communications Express Mail user who has permission to use S/MIME logs in to the Messaging Server for the first time, a series of special prompts displays about the S/MIME applet. After answering the prompts with Yes or Always, the S/MIME applet is downloaded to their computer. The applet remains on their machine until they log out of Communications Express Mail.
